Kurokawa Onsen — Relaxing at Kyushu's Premier Hot Spring Village

[Important] About the 2026 Kumamoto Earthquake

Because of the Kumamoto Earthquake of 28 July 2026, some tourist facilities and roads in Kumamoto Prefecture may be closed or impassable. Kumamoto Castle reopened on 13 August 2026, but the Kumamoto Castle Museum "Wakuwaku-za" remains temporarily closed (as of 13 August 2026). Please check the official information for each facility before you set out.

Always confirm the latest information on each facility's official website and in announcements from the local authorities before you travel.

The murmur of the river, stone paved lanes, rising steam, and inns lit by warm light: Kurokawa Onsen in Minami Oguni Town, Aso District, Kumamoto Prefecture, is one of the finest hot spring villages in Kyushu, nestled in the mountains of Aso Kuju National Park. With about 24 Japanese style inns lining the streets, its calm townscape in harmony with nature has earned high nationwide acclaim.

A Unified and Beautiful Townscape

One reason Kurokawa is so highly regarded is the townscape effort undertaken across the whole hot spring district. Each inn refrains from garish signs and neon, unifying the streets with wooden buildings and stone paved lanes. By planting groves, they have preserved a calm atmosphere that blends into nature. The result is a quietly charming hot spring village that enchants its visitors.

Bath Hopping with the Nyuto Tegata

The signature of Kurokawa Onsen is the Nyuto Tegata, a wooden bath pass introduced in 1986. It lets you visit outdoor baths of your choice among participating inns, so you can enjoy a variety of waters even without staying overnight. The adult pass allows either three outdoor baths, or two outdoor baths plus one food or souvenir exchange. From rustic outdoor baths surrounded by trees to riverside baths and cave baths, each inn has its own distinctive water, drawing crowds who enjoy hopping from bath to bath.

Access and Basic Information

The location is Minami Oguni Town, Aso District, Kumamoto Prefecture. The spring water is sulfurous among other types, offering a hot spring aroma and feel. Access is generally by car or highway bus from Aso Kumamoto Airport, JR Kumamoto Station, or the Beppu area in Oita Prefecture. As it lies among the mountains, a car is convenient, and for public transport it is wise to check service frequency in advance. The stone paved lanes can be slippery on rainy days, so comfortable walking shoes are recommended.

Practical Travel Notes

The bath pass is 1,500 yen for adults and 700 yen for children from age three to sixth grade, valid for six months from the purchase date. It can be bought at participating inns or the inn association desk known as Kazenoya. Day use bathing hours differ by inn, but a general guide is from around 8:30 to 21:00. Popular inns fill up early on weekends and during foliage season, so book overnight stays several months ahead. The village is walkable on foot, with shops offering Kumamoto specialties such as basashi horse sashimi, Aso highland vegetables, and local sweets.

One Piece of Advice

Each season has its charm, but autumn foliage and winter snow viewing baths are especially popular. Winter lantern events, in which bamboo craft is lit with candles, are enchanting and recommended. For bath hopping, bringing a towel and a small bag is handy. A stroll at dusk when the lanterns are lit offers a romantic time unique to Kurokawa Onsen.
